Pattern of acute pelvic inflammatory disease in abortion-related admissions

Sinnathuray TA, Yusof K, Palan VT, Fong CK, Adeep N, Chong CH, et al.

Am J Obstet Gynecol, 1980 Dec 01;138(7 Pt 2):868-71.
PMID: 7468674

We evaluated 3,066 consecutive women admitted during 1 year to two major hospitals of Kuala Lumpur and the adjacent urban area of Malaysia. Indicators of acute pelvic inflammatory disease were more common among patients with induced abortions. PID was thought to be a major contributor to the higher costs associated with management of patients with induced abortions.
Development and evaluation of a computer expert system for the management of fetal distress

Wong KK, Ng KH, Nah SH, Yusof K, Rajeswari K

Asia Oceania J Obstet Gynaecol, 1994 Mar;20(1):19-23.
PMID: 8172522

The general lack of specialist obstetricians in a developing country such as Malaysia prompted us to develop a computer expert system for the management of fetal distress in rural hospitals. It was based on accepted production rules and implemented on a microcomputer. The clinical prototype was evaluated by 8 specialist obstetricians and 21 non-specialist doctors involved in obstetric care. The initial impression was that this type of expert system may help in diagnosis, decision-making and teaching.

PMID: 12597515

The equitable access to quality healthcare by Malaysians has consistently been the primary objective of the Ministry of Health (MOH). The epidemiological transition to chronic illnesses, advances in medical technology, escalating healthcare costs and rising patient expectations has necessitated the strategic use of information systems in healthcare delivery. Malaysia has broken new ground by implementing a nationwide network to address inadequate access to healthcare, as well as to lower costs and achieve better health outcomes. Teleconsultation refers to the electronic transmission of medical information and services from one site to another using telecommunication technologies. This technology transforms the healthcare system by rapidly matching patient needs with the appropriate level of care however geographically remote they may be. Our findings suggest that even in these early stages of implementation, teleconsultation has led to cost savings, a more efficient allocation of resources, enhanced diagnostic options and better health outcomes.
Maternal and child health in urban Sabah, Malaysia: a comparison of citizens and migrants

Zulkifli SN, U KM, Yusof K, Lin WY

Asia Pac J Public Health, 1994;7(3):151-8.
PMID: 7794653 DOI: 10.1177/101053959400700302

This paper describes selected maternal and child health indicators based on a cross-sectional study of citizens and migrants in Sabah, Malaysia. A total of 1,515 women were interviewed from a multi-stage random sample of households in eight urban centers. Among the 1,411 women in the sample who had experienced a pregnancy before, 76% were local citizens and 24% were migrants. There were statistically significant differences between citizens and migrants in ethnicity, religion, education, household income, and access to treated water supply and sanitary toilet facilities. Significantly fewer migrants practiced any form of contraception and obtained any antenatal care during any pregnancy. Furthermore, citizens tended to initiate care as early as three months but migrants as late as seven months. Despite these differences, only the infant mortality rate, and not pregnancy wastage, was statistically significantly higher among migrants. Pregnancy interval was also similar between the two groups. The influence of several socioeconomic factors on pregnancy wastage and infant mortality was explored.

Given the magnitude of drug addiction in Malaysia, the government has given top priority to this issue. It is timely that an assessment of knowledge, attitudes and perceptions related to drug abuse and drug dependents among the general public be carried out. Thus, a nationwide survey was undertaken. A representative sample of 2,591 respondents aged 13 years and above from households were surveyed throughout the 11 states and the Federal Territory of Kuala Lumpur in Peninsula Malaysia. The results revealed that the respondents are moderately knowledgeable on drug abuse, especially information pertaining to treatment, rehabilitation and aftercare services, including education to families against drug abuse. The public possess a negative attitude towards drug dependents. Majority felt that drug addicts do not have the will power to rid themselves of drugs and they also lack a supportive family network system. Many believe that the most vulnerable group are the adolescents. Respondents were aware of the type of drugs commonly abused, although they failed to realise their long-term effects. Respondents do not attribute low education, large family and marginal income to the background of drug dependents. The findings showed gaps and misconceptions in terms of knowledge, attitudes and perceptions of the public. Accurate knowledge on, and right attitudes and perceptions towards drug related issues would certainly benefit the public in timely prevention of drug abuse.
Role of schools of public health on maternal and child health programmes in the Asia-Pacific region

Zulkifli SN, Yun-Low W, Yusof K

Asia Pac J Public Health, 1998;10(1):10-6.
PMID: 10050201

This paper assessed the role of public health schools on maternal and child health programmes in the Asia Pacific region. Economic development and its associated effects, particularly in the ASEAN countries, for example, migrant labour, ageing, environmental health, turbulence and social climate, has a tremendous impact on maternal and child health. Based on these current issues, it is evident that public health schools can play a major role in maternal and child health in terms of policy formulation and programme development. Several areas were proposed as to what schools of public health can do, namely, through networking, communication, research and training.

INTRODUCTION: The survival rate of female breast cancer survivors has been reported to be higher than other types of cancer in Malaysia. Nonetheless, breast cancer survivors face new challenges from unwanted side effects of treatment or management such as fatigue, psychological disturbance, or arm swelling, which can lead to the decline of quality of life (QOL). This study aims to adapt the Malay version of the Functional Assessment of Cancer Therapy-Breast (FACT-B) to evaluate the QOL and to test its reliability and validity in Malaysian breast cancer survivors.
METHODS: The Malay version of the FACT-B, with Disabilities of Arms, Shoulders and Hands (DASH), and Patient Health Questionnaire Anxiety-Depression Scale (PHQ-ADS) were distributed to female breast cancer survivors which were recruited on a voluntary basis, from cancer support groups based in selected states in Malaysia. Reliability was assessed based on internal consistency (Cronbach's α), whereas concurrent validity was examined by comparing domains in FACT-B with DASH and PHQ-ADS. Finally, total scores of each domain were analysed between lymphedema and without lymphedema groups for known-group validity.
RESULTS: A total of 113 breast cancer survivors agreed to participate (response rate = 100%) in the study. Our results showed that the Cronbach's α value for Malay FACT-B is 0.88, and each domain ranged from 0.62 to 0.88. A strong correlation was found between the physical well-being domain of FACT-B with DASH. Meanwhile, the breast cancer scale (BCS) displayed significant correlation with the instrument, Patient Health Questionnaire- Anxiety Depression Scale (PHQ-ADS), indicating that multiple factors including psychological distress were measured in the BCS domain. Furthermore, the instrument was able to detect differences in physical, functional and QOL between participants from lymphedema and without lymphedema groups.
CONCLUSION: The Malay version of the FACT-B demonstrated reliable properties and is effective in assessing QOL and can be applied in Malaysian breast cancer survivors.

Lymphatic vessels are regarded as the "forgotten" circulation. Despite this, growing evidence has shown significant roles for the lymphatic circulation in normal and pathological conditions in humans, including cancers. The dissemination of tumor cells to other organs is often mediated by lymphatic vessels that serve as a conduit and is often referred to as tumor-associated lymphangiogenesis. Some of the most well-studied lymphangiogenic factors that govern tumor lymphangiogenesis are the vascular endothelial growth factor (VEGF-C/D and VEGFR-2/3), neuroplilin-2 (NRP2), fibroblast growth factor (FGF), and hepatocyte growth factor (HGF), to name a few. However, recent findings have illustrated that non-coding RNAs are significantly involved in regulating gene expression in most biological processes, including lymphangiogenesis. In this review, we focus on the regulation of growth factors and non-coding RNAs (ncRNAs) in the lymphatic development in normal and cancer physiology. Then, we discuss the lymphangiogenic factors that necessitate tumor-associated lymphangiogenesis, with regards to ncRNAs in various types of cancer. Understanding the different roles of ncRNAs in regulating lymphatic vasculature in normal and cancer conditions may pave the way towards the development of ncRNA-based anti-lymphangiogenic therapy.

PMID: 2036882

With 25% of its population living in over 148 squatter settlements, with a high incidence of communicable diseases, teenage pregnancies, and psychological and familial stress, the city of Kuala Lumpur has sought ways to improve conditions. This article describes one particularly promising approach: community-based centers integrating three socioeconomic components--preschool education, maternal and child health clinics, and income-generating activities.
PIP: The accomplishments of the Sang Kancil Intervention program, a project designed to improve the living conditions of squatter communities in Kuala Lumpur, Malaysia are described. 25% of Kuala Lumpur's population lives in 148 squatter settlements, where life is especially difficult for women and children. Hoping to improve the living conditions of the urban poor, Kuala Lumpur's City hall initiated the Sang Kancil Intervention program. This program contains 3 components: preschool education, maternal and child health, and income generation. The preschool component provides education, food supplements, and medical checkups and treatment to children in the squatter settlements. In order to foster community participation, the teachers of the preschool program are chosen from among the squatter community, and mothers are encouraged to become involved. Evaluations of the preschools reveal positive attitudes from mothers and teachers, high attendance rates, and higher IQ test scores among children attending the preschool than among children not in the program. Sang Kancil has also provided maternal and health services to the squatter communities. Once a week, nurse practitioners set up a clinic providing the following services: immunization, prenatal and postnatal care, health education, nutrition, family planning, and treatment of minor illnesses. Sang Kancil's income-generation program seeks to raise the living standards of poor families by creating employment opportunities for women. Sang Kancil has established companies staffed, owned, and managed entirely by women. Among other things, these companies manufacture toys, batik items, and ceramics. The success of the companies has pushed shareholders above the poverty line.

PMID: 8889409

A survey was carried out to gather information on knowledge, attitudes and perception of parents and their children in relation to drug abuse matters. Significantly more teenagers knew more of the cause of drug addiction, as well as places for treatment and rehabilitation. Both teenagers and parents were also aware of reasons why drug addicts find it difficult to change their habits, mainly lacking motivation to stop taking drugs and that drug addicts do not have the power to control themselves. Teenagers were significantly more aware of effects of negative parental attitudes contributing to drug abuse, apart from school factors. Personal experiences before abusing drugs such as knowledge of pleasurable effects of drugs and where to obtain them has also a role to play in leading to drug abuse. There was also agreement that unfulfilled needs such as 'not being respected recognised for ones capabilities' and 'not being loved or treated fairly by parents', were causes of drug abuse. Significantly more teenagers knew of the ways of abusing drugs, mainly by injection, smoking and sniffing, and also sources of information via the mass media, social clubs, rehabilitation centres and schools. However, both the parents and teenagers were relatively ignorant of the long term effects of abusing drugs.

Purpose. Type 2 diabetes consists of progressive hyperglycemia and insulin resistance, which could result from glucose toxicity, inflammatory cytokines, and oxidative stress. In the present study we investigated the effect of Gelam honey and quercetin on the oxidative stress-induced inflammatory pathways and the proinflammatory cytokines. Methods. HIT-T15 cells were cultured and preincubated with the extract of Gelam honey (20, 40, 60, and 80 μg/mL), as well as quercetin (20, 40, 60, and 80 μM), prior to stimulation by 20 and 50 mM glucose. Results. HIT-T15 cells cultured under hyperglycemic condition showed a significant increase in the inflammatory pathways by phosphorylating JNK, IKK-β, and IRS-1 at Ser307 (p < 0.05). There was a significant decrease in the phosphorylation of Akt at Ser473 (p < 0.05). Pretreatment with Gelam honey and quercetin reduced the expression of phosphorylated JNK, IKK-β, and IRS-1, thereby significantly reducing the expression of proinflammatory cytokines like TNF-α, IL-6, and IL-1β (p < 0.05). At the same time there was a significant increase in the phosphorylated Akt showing the protective effects against inflammation and insulin resistance (p < 0.05). In conclusion, our data suggest the potential use of the extract from Gelam honey and quercetin in modulating the inflammation induced insulin signaling pathways.
Fulltext Protective effect of palm vitamin E and α-tocopherol against gastric lesions induced by water immersion restraint stress in Sprague-Dawley rats

Indian J Pharmacol, 2008 Mar;40(2):73-7.
PMID: 21279170 DOI: 10.4103/0253-7613.41042

OBJECTIVE: Stress can lead to various changes in the gastrointestinal tract of rats. The present study was designed to compare the effect of palm vitamin E (PVE) and α-tocopherol (α-TF) supplementations on the gastric parameters important in maintaining gastric mucosal integrity in rats exposed to water immersion restraint stress (WRS). These parameters include gastric acidity, plasma gastrin level, gastric prostaglandin E(2) (PGE(2)), and gastric lesions.
MATERIALS AND METHODS: Sixty male Sprague-Dawley rats (200-250 g) were divided into three equal groups: a control group, which received a normal rat diet (RC), and two treatment groups, receiving oral supplementation of either PVE or α-TF at 60 mg/kg body weight for 28 days. Each group was further divided into two groups: the nonstress and stress groups. The stress groups were subjected to 3.5 h of WRS once at the end of the treatment period. Blood samples were then taken to measure the gastrin level, after which the rats were killed. Gastric juice was collected for measurement of gastric acidity and gastric tissue was taken for measurement of gastric mucosal lesions and PGE(2).
RESULTS: Exposure to stress resulted in the production of gastric lesions. PVE and α-TF lowered the lesion indices as compared to the stress control group. Stress reduced gastric acidity but pretreatment with PVE and α-TF prevented this reduction. The gastrin levels in the stress group were lower as compared to that in the nonstress control. However, following treatment with PVE and α-TF, gastrin levels increased and approached the normal level. There was also a significant reduction in the gastric PGE(2) content with stress exposure, but this reduction was blocked with treatment with both PVE and α-TF.
CONCLUSION: In conclusion, WRS leads to a reduction in the gastric acidity, gastrin level, and gastric PGE(2) level and there is increased formation of gastric lesions. Supplementation with either PVE or α-TF reduces the formation of gastric lesions, possibly by blocking the changes in the gastric acidity, gastrin, and gastric PGE(2) induced by stress. No significant difference between PVE and α-TF was observed.

Background. Oxidative stress induced by reactive oxygen and nitrogen species is critically involved in the impairment of β -cell function during the development of diabetes. Methods. HIT-T15 cells were cultured in 5% CO2 and then preincubated with Gelam honey extracts (20, 40, 60, and 80 µg/mL) as well as quercetin (20, 40, 60, and 80 µM), prior to stimulation by 20 and 50 mM of glucose. Cell lysate was collected to determine the effect of honey extracts and quercetin on the stress activated NF- κ B, MAPK pathways, and the Akt (ser473) activated insulin signaling pathway. Results. HIT-T15 cells cultured under hyperglycemic conditions demonstrated insulin resistance with a significant increase in the levels of MAPK, NF- κ B, and IRS-1 serine phosphorylation (ser307); however, Akt expression and insulin contents are significantly decreased. Pretreatment with quercetin and Gelam honey extract improved insulin resistance and insulin content by reducing the expression of MAPK, NF- κ B, and IRS-1 serine phosphorylation (ser307) and increasing the expression of Akt significantly. Conclusion. Gelam honey-induced differential expression of MAPK, NF- κ B, IRS-1 (ser307), and Akt in HIT-T15 cells shows that Gelam honey exerts protective effects against diabetes- and hyperglycemia-induced oxidative stress by improving insulin content and insulin resistance.
Illegal abortion: an attempt to assess its cost to the health services and its incidence in the community

PMID: 3733306

This article describes a study designed to test a method for assessing the cost to the health services of illegally induced abortion and the feasibility of estimating the incidence of induced abortion by a field interviewing approach. The participating centers included three hospitals in Ankara, Turkey; three hospitals in Ibadan, Nigeria; one hospital in Caracas and one in Valencia, Venezuela; and two hospitals in Kuala Lumpur, Malaysia. Hospitalized abortion cases were classified as induced or spontaneous or as "probably induced," "possibly induced," or "unknown" according to a classification scheme comprising certain medical criteria. The sociodemographic characteristics of induced and spontaneous abortion cases were subjected to discriminant function analysis and the discriminating variables best characterizing the induced versus the spontaneous abortion groups were identified for each center. On the basis of this analysis, the "probably" and "possibly" induced and "unknown" categories were further classified as induced or spontaneous abortion, with stated probabilities. Thus an overall estimate is made of the proportion of all hospitalized abortions that can be considered illegally induced outside the hospital. Selected results on costs of induced and spontaneous abortion are shown. The method further tested the feasibility of obtaining valid survey data on abortion from the communities studied by re-interviewing the women hospitalized for induced and spontaneous abortion six months later in their homes. This exercise showed a degree of under-reporting of abortion that varied widely among centers, even among women who had admitted illegal induction at the time of hospitalization. The feasibility of estimating the incidence of illegal abortion by field studies is discussed in the light of these findings.
Fulltext Soil moisture uniformity under low-pressure sprinkler irrigation system

The use of a sprinkler irrigation system is becoming more popular to reduce water
consumption and increase irrigation efficiency. Irrigation uniformity plays an important role in the
performance of the sprinkler irrigation system. The use of low operating pressure instead of high
operating pressure system offer many benefits including energy and water saving. An experimental
study was performed using two systems; a square 12x12 m system and a rectangular 10x12 m system
to investigate irrigation uniformity based on soil moisture content of the sprinkler irrigation system
under low operating pressure. In addition, irrigation uniformity was compared based on water
application and soil moisture content. In this study, different low operating pressures (62, 82, 102 and
122 KPa) were selected. Different nozzle diameters (4, 5, 6 and 7 mm) and different riser heights (0.5,
0.75, and 1.0 m) were also used. The soil moisture content uniformities of 10 min after irrigation are
more dependent on the initial soil moisture content uniformity than any other design factor. It is also
less influenced by water application uniformity.

The purpose of this study was to determine the spectrum of nasal involvement in systemic lupus erythematosus (SLE) and its association with the disease activity of SLE based on the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). This was a cross-sectional and observational study involving 73 stable SLE patients. All subjects were evaluated for the SLEDAI scores and had nasal endoscopic examination. The most commonly reported symptom was nasal congestion (31.5%) followed by nasal itchiness (26.0%), runny nose (20.5%) and nasal dryness (19.2%). Almost half (42.9%) of the subjects had nasal mucosal abnormalities, which included mucositis, crusting, ulceration, bifid middle turbinate, septal spur, Jacobson's organ, deviated nasal septum, bilateral inferior turbinate hypertrophy, everted uncinate process, nasopharynx cleft and torus palatinus. The median SLEDAI score for subjects with nasal symptoms was significantly higher than subjects without nasal symptoms (p
